Özet

In this study, ZnO nanoparticles were synthesized using a sonochemical method at room temperature.

Also, 17-4 PH stainless steel foam had high porosity (70%), strength and good corrosion resistance, was

produced by the space holder-water leaching technique. We coated 17-4 PH stainless steel foam with

the ZnO nanoparticles and characterized using SEM and FTIR. The aim of this study was to synthesize

the novel ZnO nanoparticles, which coated 17-4 PH stainless steel foam and investigated the surface

characteristics of the ZnO nanoparticles using Du Nouy ring method. The effect of the operating

parameters such as the mass fraction (1%, 5%, and 10%) of silica, the concentration (1-100 ppm),

sonication time (1-15 min), the amplitude of sonication (10-40 %), and temperature (25-45 oC) on the

surface tension of synthesized nanoparticles was investigated. This study provided a mathematical

model to describe the effect of ZnO nanoparticles on the surface tension for colloidal solutions. ZnO

nanoparticles coated 17-4 PH stainless steel foam as a novel promising nanomaterial for biomedical

applications was presented.
